BACKGROUND: The reflex cough test is useful for detecting silent aspiration, a risk factor for aspiration pneumonia. However, assessing the risk of aspiration pneumonia requires measuring not only the cough reflex but also cough strength. Currently, no reflex cough testing device is available that can directly measure reflex cough strength. We therefore developed a new testing device that can easily and simultaneously measure cough strength and the time until the cough reflex, and verified whether screening with this new instrument is feasible for evaluating the risk of aspiration pneumonia...

BACKGROUND: Even though the diagnosis of chronic obstructive pulmonary disease (COPD) is easy and based mainly on spirometry and symptoms, the prevalence of underdiagnosis is extremely high. The use of simple screening tools (e.g., questionnaires, hand-held spirometers) has been proved to be a simple method for case finding of COPD. Nevertheless the most appropriate target group of the general population has not been specified yet. OBJECTIVES: The aim of the present study was to compare 3 screening questionnaires among smokers aged >40 years in the primary care setting...

OBJECTIVE: We propose a remote, non-invasive approach to develop Pulmonary Function Testing (PFT) using a depth sensor. METHOD: After generating a point cloud from scene depth values, we construct a 3D model of the subject's chest. Then, by estimating the chest volume variation throughout a sequence, we generate volume-time and flow-time data for two prevalent spirometry tests: Forced Vital Capacity (FVC) and Slow Vital Capacity (SVC). Tidal volume and main effort sections of volume-time data are analysed and calibrated separately to remove the effects of a subject's torso motion...
